tidb測試環境安裝，離線部署

1.環境以及規劃

  機器:centos7.5 ; 文件系統爲ext4；內存16g；cpu8核，共三個節點； 

      ip             hostname                    roles

 10.40.20.66        vm-10-40-20-66         tidb  tipd  tikv
 10.40.20.67        vm-10-40-20-67         tidb  tipd  tikv
 10.40.20.92        vm-10-40-20-92               tipd  tikv

 

2 .本地下載tidb-ansible-master.zip，上傳到中控機，而後重命名爲tidb-ansible;

3.安裝ansible：

sudo yum -y install python-pip curl

sudo yum -y install sshpass

cd tidb-ansible

sudo pip install -r requirements.txt     

[tidb@vm-10-40-20-66:/opt/Jinja2-2.9.6]$ cat /home/tidb/tidb-ansible/requirements.txt 
ansible>=2.4.2
jinja2>=2.9.6
jmespath>=0.9.0

sudo pip install -r requirements.txt會報錯缺乏依賴包，因爲集羣沒外網，去http://mirrors.aliyun.com/pypi/simple/鏡像去下載python依賴包到本地，再上傳到中控機：
Jinja2-2.9.6.tar.gz；jmespath-0.9.1.tar.gz；MarkupSafe-0.23.tar.gz ，注意版本匹配;
各個python包解壓后里面都有一個setup.py腳本，使用以下命令安裝：

python setup.py install

4.建立tidb用戶，設置免密碼登陸，配ntp同步；

ansible -i hosts.ini all -m shell -a  "ntpstat" -b

ansible -i hosts.ini all -m shell -a  "ntpq -p" -b

5.編輯host.ini:

[tidb@vm-10-40-20-66:~/tidb-ansible]$ cat hosts.ini 
[servers]
10.40.20.66
10.40.20.67
10.40.20.92

[all:vars]
username = tidb
ntp_server = pool.ntp.org

  6.編輯invertory.ini:

## TiDB Cluster Part

[drainer_servers]

## Group variables
[pd_servers:vars]
# location_labels = ["zone","rack","host"]

## Global variables
[all:vars]
deploy_dir = /data/tidb/deploy

## Connection
# ssh via normal user
ansible_user = tidb

cluster_name = leochen-cluster

tidb_version = v2.0.7

# process supervision, [systemd, supervise]
process_supervision = systemd

timezone = Asia/Shanghai

enable_firewalld = False
# check NTP service
enable_ntpd = True
set_hostname = False

## binlog trigger
enable_binlog = False
# zookeeper address of kafka cluster for binlog, example:
# zookeeper_addrs = "192.168.0.11:2181,192.168.0.12:2181,192.168.0.13:2181"
zookeeper_addrs = ""
# kafka cluster address for monitoring, example:
# kafka_addrs = "192.168.0.11:9092,192.168.0.12:9092,192.168.0.13:9092"
kafka_addrs = ""

# store slow query log into seperate file
enable_slow_query_log = False

# enable TLS authentication in the TiDB cluster
enable_tls = False

# KV mode
deploy_without_tidb = False

# Optional: Set if you already have a alertmanager server.
# Format: alertmanager_host:alertmanager_port
alertmanager_target = ""

grafana_admin_user = "admin"
grafana_admin_password = "admin"


### Collect diagnosis
collect_log_recent_hours = 2

enable_bandwidth_limit = True
# default: 10Mb/s, unit: Kbit/s
collect_bandwidth_limit = 10000

7.安裝tidb集羣：

安裝前檢驗

執行如下命令若是全部 server 返回 tidb 表示 ssh 互信配置成功。

ansible -i inventory.ini all -m shell -a 'whoami'

執行如下命令若是全部 server 返回 root 表示 tidb 用戶 sudo 免密碼配置成功。

ansible -i inventory.ini all -m shell -a 'whoami' -b

下載安裝包，上傳到downloads目錄：

8.編輯bootstrap.yml文件，不符合的能夠暫時註釋掉，測試環境機器配置不高；

9.ansible-playbook bootstrap.yml；

10.ansible-playbook deploy.yml；

11.ansible-playbook start.yml；

12 . 使用 MySQL 客戶端鏈接測試，TCP 4000 端口是 TiDB 服務默認端口。 

[tidb@vm-10-40-20-66:~/tidb-ansible/downloads]$ mysql -u root -h 10.40.20.66 -P 4000
